T a/ZZ whom, it may concern: v

Be it known that I, HENRY BETHU Y a citizen of the United States,residing at Emmett, county of lVayne, State of Michigan, have invented acertain new and useful Improvement in Threshing-Wlachines; and I declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains t0 make and use the same,reference beinghad to the accompanyingdrawings, which form a partr of this speeiiication.

My inventionrelates to an improvement in threshing-machines shown in theaccompanying drawings, and more particularly set forth in the followingspecification and claims.

In the drawings, Figure l is a longitudinal vertical section of athreshing-machine,showing my improvement installed; Fig. is across-sectional view through a portion of the machine. Fig. 3 is a faceview of the means employed for governing the raising and lowering of thetoothed barsfor conveying the straw, showing the switch controlling thesame in Fig. et is a similar view showing the switch thrown in theopposite direction. Fig. 5 is a view from the opposite side on a smallerscale, showing the links connecting the rocking-arm with the blockscontrolling the movement of the switch. Fig. G is a cross-sectional viewthrough Fig. 4, showing the part attached to the frame of the machine.Fig. 7 is a detail of the hanger suspended from the frame supporting thetoothed bars.

The obj ect of my invention is to provide an attachment forthreshing-machines controlling the raising and lowering of the toothedbars which convey the straw forward by their reciprocatory movement, oneof the objects in view being to insure a positive movement providingmeans which will not readily get out of order and which is capable ofadjustment, whereby the toothed bars may be given more or lessinclination, as may be desired, the raising and lowering of the toothedbars being positive at whatever angle they may be set.

Referring to the letters of reference shown in the drawings, Arepresents the frame of the threshing-machine; B, the toothed bars forconveying the straw supported by the members C.

` D is a pitman, one end being connected with the driving crank-shaft E,the other end engaged with the member C.

FY represents hangers suspended from the members C, supporting afriction-roll f.

G is a casting, preferably disk-shaped, with slotted channels g, formedon an arc of a circle, for the passage of bolts g', engaging the castingwith the frame of the threshing-machine on the inside.

G" is a channel formed in the casting, and Il is a switch provided witha journal 7L, having its bearing in a hub formed in the casting G, saidjournal being squared at h' to receive a rocking arm I, mounted thereon.

h2 is a locking-nut to secure the arm I on the journal.

I represents links connecting the rocking arm with blocks I2, travelingin the channel Gf. Elongated slots are formed Vin the channel back ofthe blocks, through which the bolt travels connecting the block with thelinks I.

The operation of the improvement will be readily understood. Thefriction-rolls f, supported by the hangers F, secured to the member C,travel in the channels G', formed in the casting G. Then the pitman Dforces the bars C forward, the friction-roll travels along the upperedge of the channel G', forcing the switch H down, as shown in Fig. 4.,the switch remaining in this position until the frictionroll fcomes incontact with the block I2, forcing the block forward and in so doingthrowing the switch into the position shown in Fig. 3. The members Chaving reached the limit of their upward movement, the friction-roll Fon the return movement is directed downward by the switch Il, the rolltraveling around the arc of a circle formed by the channel G', and in sodoing' opens up the passage to the rear block I2, throwing the switchinto the position shown in Fig. 4. As the member C reaches to the limitof its backward movement, the block l2 is forced by the frictionroll tothe end of its movement, as shown in Fig. 3, throwing the switch intothe position shown in that figure. rlhe forward movement of the member Cagain throws the switch down, as shown in Fig. 4, and the operation justdescribed is repeated. If for any reason it is desired to vary the angleof the toothed straw-conveyors, the bolts g' are loos- IOC ened and thecasting G rotated within the limit of the travel of said bolts in theslot'g and the bolts again set. It is obvious that other means ofadjusting this plate may be employed and the same come within the scopeof this invention. l

Having thus described my inventon,wl1at I claim isl. Inathreshing-machine, means for giving a vibratory movement to thestraw-carrier co nsisting of two channels in the frame of the machine,one of which takes a delective course from the other, a traveler securedto the frame of the straw-carrier traveling within said channels, aswitch to direct the course of the traveler from one channel to theother, and means operated by the impact of the traveler to throw theswitch, substantially as described.

2. In a threshing-machine, means for giving avibratory movement to thestraw-carrier consisting of a casting secured to the frame of themachine provided with two channels, a traveler secured to the frame ofthe straw-carrier, av switch pivoted in said casting to direct themovement of the traveler in one channel and then to the otheralternately, a rocking arm secured to the journal of said switch, blockstraveling in the channels to receive the impact of the traveler, and alink connection between the rocking arm and said blocks whereby theimpact of the traveler against one of the blocks will throw the switchin one direction and its impact against the other block will throw itinthe opposite direction, substantially as described.

3. In a threshing-machine, means for giving a vibratory movement to thestraw-carrier, a casting secured to the frame of the machine providedwith two channels, one or" which takes a delective course from theother, a hanger secured to the frame of the straw-carrier supporting afriction-roll traveling within said channel, a switch pivoted in saidcasting to govern the direction taken by said frictionroll, a rock-armsecured to the journal of the switch, abutting-blocks to receive theimpact of the friction-rolhlink connection between the blocks and therock-arm, and means for givin g the straw-carrier a reciprocatingmovement, substantially as described.

4L. In a threshing-machine, means for giving avibratory movement to thestraw-carrier consisting of a casting secured to the frame of themachine provided with two channels, one of which takes a deflectivecourse from the other, a traveler secured to the frame of thestrawcarrier traveling within said channels, and means whereby saidcasting may be rotated on its own axis to give a greater or lessinclination to said channels, substantially as described.

5. In a threshing-machine, means forgiving avibratory movement to thestraw-carrier consisting of a casting secured to the frame of themachine provided with two channels, one of which takes a deiectivecourse' from the other, a traveler secured to the frame of thestrawcarrier traveling within said channels, means whereby said castingmay be rotated on its own axis to give a greater or less inclination tosaid channels, means consisting of one or more segmental slots for thepassage of bolts through said casting to secure the same to the frame ofthe machine, and the bolts, substan.-

tially as described.

In testimony whereof I sign this specification in the presence of twowitnesses.
